Unfortunately, the TIFF format you see listed there is not a raw file.
It's nothing but an ordinary TIFF file holding 24 bits/pixel image data.
There's no more data there than in a JPEG except for the compression.
The Olympus format allows you to control the compression ratio on
JPEGs so you could likely do as well using a low compression ratio JPEG
and at much less space.
Bite the bullet and use raw with post processing for the best results.
The raw format says that it's not compressed but it has to have some
sort of compression to fit into the 13.6 MB raw file. I wouldn't worry
about the proprietary format. There are many pieces of software (free
and not free) that know that format. If you can get along with the Oly
software interface it will do a good job on conversion.

While I was going through the menu on my new/used E-500, I came up to
the recording format setting and was reminded that there is a TIFF
format that saves 24.5M raw images. I'm interested in knowing how
this compares with the Olympus proprietary raw format. The TIFF
format is 50% larger in file size, but it would be more robust as it
could be imported into just about any graphics package you can name.
In our discussion last year about the problems with using digital
cameras for B&W, I recall that some people preferred the raw format
for processing, but I don't recall the TIFF raw format being
mentioned.
